Title: Detecting element for inflammable gas
Inventor: TAKUBO YONEJI
IPC: G01N33/00
Filed: 1980-10-02
Abstract: PURPOSE:To detect gas in discrimination of sorts, by a method wherein a gas sensing body having sensitivity of different temperature dependent property corresponding to sorts of gas is supplied with temperature distribution. CONSTITUTION:Ferric chloride and ferrous sulfate are dissolved in water and ammonium hydroxide is added thereto and coprecipitation is obtained. The coprecipitation is put into a reduced pressure vessel and dried in vacuum state and then heated into powders. Triethanol amine is added to the powders, and the obtained paste is applied onto an alumina substrate 8 and then baked into a sintering film 7. On rear surface of the alumina substrate 8 is installed a heater of zigzag form to heat the  gas sensitive film 7 to about 400 deg.C at inner two elements and to about 350 deg.C at outer two elements. When, for example, the electrode 1 and the electrode 3 are shorted to constitute a bridge circuit and suitable voltage is impressed between the electrodes 2 and 5, the detecting element measures voltage between the electrode 4 and the electrode 1 (or 3). Since voltage variation to methane gas is small in comparison to other gas, methane can be detected in discrimination from other gas.

Title: Pump starting operation in pumping-up power station
Inventor: SATOU SHINSAKU
IPC: F04B49/06
Filed: 1983-07-30
Abstract: PURPOSE:To permit a power generator and a motor to be set in parallel into a same electric power system stably and simultaneously by idly operating each pump by pushing-down the water surface and simultaneously and driving a plurality of synchronous motors directly connected to the respective pumps by the electric power supplied from a synchronous power generator directly connected to a water wheel driven. CONSTITUTION:A power generator 2 and a motor 4a are electrically connected, and a pump 3a is started by opening the guide vane of a water wheel 1 after the water-surface is pushed-down by the supplied air, and a runner is exposed to the air, and the pump 3a is idly operated by supplying electric power into the motor 4a from the power generator 2 driven. When a rated revolution speed is reached, the power generator 2 and the motor 4a are set in parallel to a same electric power system outside. In this case, the opening degree of the guide vane of the water wheel 1 is controlled so that the relative difference between the power generation output supplied into the electric power system by the power generator 2 and the water pumping-up output received by the motor 4a is set within a prescribed range. When the transfer to water pumping- up operation is completed after the exhaust and water filling operation for the pump 3a, the power generator 2 is released from the system and set into stop state. Therefore, the influence exerted onto the electric power system by the pump input can be averted.

Title: Controlling method of image density in copying machine
Inventor: NAKAYA FUMIO
IPC: G03G15/08
Filed: 1982-08-13
Abstract: PURPOSE:To stabilize an image density without receiving the influence of fluctuating factors, by controlling the electric current of an electryfier according to the setting of the potential in a dark part, regulating the quantity of light of an exposing device according to the setting of the potential in a bright part, and controlling the replenishing of a toner with the inclination of a development curve. CONSTITUTION:When the measured potential in a dark part is lower than an ideal value, the signal instructing the increase in an output current is supplied as a control signal 9 to a control circuit 7 for electrostatic charging current. When said potential is high, a decrease in the output current is instructed. The potential in the bright part is detected with a probe 4 for measuring surface potential and is calculated with a surface electrometer 8. The calculated potential is compared with a reference potential by the 2nd comparator contained therein and quantity of light of an illumination lamp 3A is changed by a control circuit 16 for exposure to control the potential in the bright part so that said potential is made equal to the reference value. The potential V(CUT) at the point where the extension of a development curve 21 intersects with the X-axis is determined, where the final potential in the bright part is designated as V(BKG) and the inclination of the curve 21 as gamma. A control circuit 19 for development outputs a control signal 25 for development bias from the value V(BIAS) of the equation I according to said values. The fluctuation in the image density owing to a change in the developability of the developer is thus prevented.
